Title:

THERMALLY CONVERTIBLE LITHOGRAPHIC PRINTING PRECURSOR COMPRISING AN ORGANIC BASE

Document Type and Number:

WIPO Patent Application WO2002066252

Kind Code:

A8

Abstract:

In accordance with the present invention there is provided an imaging element for lithographic offset printing. The imaging element comprises hydrophobic polymer particles in an aqueous medium, a substance for converting light into heat, and an organic base. The imaging element may be used for printing long run lengths on lower quality paper and in the presence of set-off powder. The imaging element may be imaged and developed on-press and may be sprayed onto a hydrophilic surface to create a printing surface that may be processed wholly on-press. The hydrophilic surface may be a printing plate substrate or the printing cylinder of a printing press or a seamless sleeve around the printing cylinder of a printing press. This cylinder may be conventional or seamless.
